GLP-1 medications like Ozempic and Wegovy may weaken the connection between impulsivity and violent behavior, according to a Rutgers University study published in the journal Criminology. Researchers found that the link between impulsivity and violence was 62% weaker among current medication users compared to those who had used the drugs in the past.
How do GLP-1 drugs influence violent behavior?
Researchers investigated whether GLP-1 receptor agonists, which are widely used for weight management and diabetes, impact violent criminal actions in adults. The study analyzed data from a 2025 survey involving 7,521 adults across the United States, specifically focusing on a subgroup of 821 people who had used GLP-1 medications.
The research team compared current medication users against former users to see how the drugs affected the relationship between behavior and specific triggers. According to Daniel Semenza, the study’s lead author and director of research at the New Jersey Gun Violence Research Center, the most significant finding involved impulsivity.
“The strongest finding in the study was that the well-established link between impulsivity and violent behavior was substantially weaker among current GLP-1 users compared to former users,” Semenza stated. He noted that as these medications become more common, understanding their potential effects on public safety is essential.
While impulsivity-related violence dropped by 62% in current users, the link between alcohol use and violence was approximately 52% weaker, though this finding was less consistent across sensitivity analyses.
Comparing current and former users
The study’s data suggests that the medication doesn’t necessarily eliminate the impulse itself. Instead, it appears to change how that impulse translates into action. This distinction is critical for understanding how these drugs might interact with human psychology and social behavior.
Why is the link between impulsivity and alcohol weakening?
Across the entire survey sample, researchers observed that higher impulsivity and increased alcohol consumption typically correlate with higher rates of violent behavior. However, these correlations were significantly less pronounced in the group currently taking GLP-1 medications.
Christopher Thomas, an assistant professor at Rutgers University-Camden and coauthor of the study, compared the medication’s effect to psychological intervention. “Our findings are consistent with these medications working like cognitive behavioral therapy, weakening the path from impulse to action rather than eliminating impulsivity itself,” Thomas said.
This suggests the drugs might provide a “buffer” period between a person’s immediate urges and their physical response. While the 52% reduction in the alcohol-to-violence link was notable, the researchers mentioned that these specific results were not as stable across all parts of their analysis as the impulsivity data.
What are the limitations of this research?
The Rutgers team cautioned that this study does not prove GLP-1 medications directly cause a reduction in crime. Because the research was observational and cross-sectional, it can only identify associations. It cannot definitively establish a cause-and-effect relationship.
Several factors could influence these results, including lifestyle changes that often accompany weight loss or changes in diet that occur when using GLP-1 agonists. To reach a definitive conclusion, the researchers stated that future longitudinal and experimental studies are required.
These future studies will aim to determine if the medications truly lower the risk of violence and will attempt to uncover the specific biological and behavioral mechanisms driving these changes.
Frequently Asked Questions
No. According to coauthor Christopher Thomas, the drugs appear to weaken the path from an impulse to an action, rather than removing the impulsivity itself.
No. The Rutgers University study is observational, meaning it shows a correlation between medication use and reduced links to violence, but it does not prove causation.
The study was conducted by researchers at Rutgers University, including Daniel Semenza and Christopher Thomas, and was published in the journal Criminology.
